Definitions
- the thermal treatment in question consists in a residence at a high temperature (of between 300 and 700°C) in the presence of oxygen.
- the temperature during the thermal treatment is preferably greater than or equal to 400°C, or even greater than or equal to 500°C, in order to increase the efficiency of the regeneration.
